Answer: 8%
Step-by-step explanation:
Answer:
<h3>Part A</h3>
- <em>The graph is attached</em>
<h3>Part B</h3>
For zero number the cost is zero and the rate of change is 25.
- 0 - 0, 1 - 25, 2 - 50, 3 - 75, 4 - 100
This is the indication of the proportional relationship
<h3>Part C</h3>
- It is a constant change as the difference is same for each step - 25
- The ordered pair (1, 25) shows the unit rate is $25 per pair of shoes
<h3>Part D</h3>
- Constant of proportionality is 25
<h3>Part E</h3>
<u>The equation is:</u>
where y - cost, x - number of pairs of shoes, 25 - constant of proportionality
answer: she is right that y = 29, but step three should be addition property of equality.
work: let's see how she worked to isolate y. she started by subtracting 2y from both sides, so so far she is correct. after that, she added 84 to both sides, and again that is a correct step, but her proof is wrong, since you are adding and not subtracting 84, it's the addition property of equality. lastly, she divided 145 by and correctly got 29. so yes, she is correct.
